Reasons for rejection

Condition

1. Refer to general vehicle pages.

2. A device fitted to a vehicle to restrict the field of swing of a driveshaft in the event of driveshaft failure is:

a) missing, where there is evidence that one was originally fitted, or

b) not securely attached, or

c) cracked, or

d) significantly deteriorated or damaged so that it is unlikely to prevent the driveshaft from striking the ground, chassis or floor in the event of driveshaft failure, or

e) showing evidence of contact with the driveshaft.

Modification

3. A modification or repair affects the engine or transmission and:

a) is not excluded from the requirements for HVS certification (Table 13-1-2), or

b) the modification is not for the purpose of law enforcement or the provision of emergency services, or

1. Significant work involving:

a) relocation of components

b) fitting of components that are not identical to OE components

c) modification of components.

1. Any modification or repair likely to have been carried out before 1 January 1997 (modifications and repairs before this date generally required certification but for inspection purposes no evidence of this is required).
